Years ago me and a couple of mates built mini shallow-level submarines. Initially they were remote controlled, then programmable (since radio waves don't like water) and eventually we got to the point where they could travel a few miles at a time underwater, surface enough to expose their GPS antennae to confirm a fix and link to Meshtastic for updated instructions, and then carry on their way. My point is these smugglers need to get their shit together. "Mother ships"? Give me a break. Amateurs.
